That's good you can use it there. In Canada for sure, but didn't realize a US-based card can be used in EU.

I know the couple of places I've inquired in Asia it doesn't work. India for sure (It's Tata Starbucks there - joint venture with Tata due to ownership rules). Also in Indonesia they said it wouldn't work, but I didn't really try since I only had my digital card with me and they don't have the readers for it. I also tried to register cards from both in my US account, but it wouldn't work, so would also be surprised if they would take the US card.
